There are so many greedy people in the world.
"People are praying for one country only, when the rest is suffering." --At least they're praying. It's not that they don't care about the others, they may not even be aware of it. At least they prayed for what they were aware of.
Instead of insulting those that have prayed and sent their support, and questioning WHY they ONLY prayed for that particular reason; ask yourself if you know every single horrible event that is happening in the world. Did you pray or give support for each one? Did you make sure that you made others aware of all of it? Instead of criticizing and saying not to join the singular support of flags because "if you're planning to support one, you should support every single one; if you're not planning to do it, don't even bother." Ask yourself, why the hell isn't the animal welfare society helping out the home for the elders? Why on Earth are the charities for cancer not supporting the charities for the sick and dying children on streets? Because they all have their own causes and that doesn't mean that promoting theirs does harm for the others. You should be glad that people are at least trying to support what they could.
This is not a separation of Samaritans or a flaw in trying to find peace. Insulting those that support their individual choices and telling them that they should only do it if they support everyone else, is different from making people aware of the others that are also suffering.
This is exactly how peace is eliminated. Everyone's so greedy of their own peace, their logic becomes skewed. "If I can't have it, then you can't." "If you won't give it to me, then no one should have it."
Don't add negativity to those that are trying to support their cause. As long as it's not derogatory, just support yours and everything else you believe in. Don't be greedy and full of pride. You'll just fill yourself with disgrace.
